  Summary

  This Service Information bulletin announces availability of a new control valve assembly (valve body) designed to prevent false detection of DTC P0841 and / or illumination of the AT Temp light. Testing has revealed in some limited cases, air bubbles (aerated fluid) may enter certain pressure circuits within the control valve assembly causing fluid pressure control and adjustment to be calculated incorrectly resulting in DTC P0841. The shape of these circuits has been changed to prevent this occurrence.

  Summary

  This Service Information bulletin announces a design change to the clutch release bearing used on the models as listed above. During assembly of the bearing, a different type of grease is used which has a higher resistance to heat. In cases where the operator keeps a foot on the clutch pedal for extended periods, an increased amount of heat is generated which can cause the grease inside the bearing to deteriorate. In a case of prolonged clutch pedal application, seizure of the bearing can occur with potential damage to other related components.
